HP 7475A Plotter

DId you find a > source for pens? Also, do you have any idea where I can get a > plotter manual? Even xerox copies of the important pages would > help. ALso, any idea what cable is required. Thanks. As other folks have written, the pens come up on ebay sometimes. They might be OK -- HP sold them with expiration dates and I don't really know how well they keep, although (a) back in the 1980s we didn't pay much mind to the expiration date on the package and had no cause to regret it and (b) a friend who has purchased pens via ebay has said that at least some of them were OK. The pens do dry out if left in the plotter though, even if they are capped by the plotter or the pen carousel. I would not expect pens to work unless they are in sealed packages. HP no longer sells pens. Last time I looked their web site referred users to Koh-i-noor for pens and ink, and I think I managed to work out that Koh-i-noor had refillable ink pens as well as new felt-tip pens. The 7475A is tricky and you may need more than pinouts for its port, because if it's an RS-232 flavor, the DIP switches let you tell it whether to behave like a terminal device or as an eavesdropper on an existing terminal device's connection. To use it from a PC based application you probably want the former; the latter is useful for host-based graphics applications that are accessed from a terminal but know of the existence of the eavesdropping plotter. -Frank McConnell

That means that only a few CD-ROM drives will be bootable, such as Toshiba 3301, 3401, and a few old Sony drives -- and all of those will need to be set up correctly.

Acoustic Coupled Modems & papertape....

Hole spacing is 0.1". 8-level tape is 1" wide, with 3 holes, then a smaller-diameter sprocket hole, then 5 holes. There also exist 7- and 5-level tapes which are simply narrower (3+1+4, 3+1+2), and maybe also a six-level tape but I don't know what used it. Somewhere I have what looks to be a parallel tape reader with a knob that rotates different-width guides into place, but it has no manufacturer information. -Frank McConnell

All the newer Toshibas -- and most other SCSI-2 CD-ROMs -- will accept the appropriate MODE SELECT command. The 3201, 3301, and 3401 all have internal jumper pads to hardwire the block size.

Eagle II?

by jeff.kaneko＠juno.com

According to _The_Microcomputer_Buyers_Guide_ (1983 edition): "The Eagle II, III, and IV integrate the the CPU, memory, disk storage, CRT, display, and keyboard into one desktop unit. The basic features common to all systems are: Z80A CPU (4Mhz); 64Kb of memory,; two serial I/O ports; one Centrinonics compatible parallel port; one paprllel port for hard disk expansion; 12" green CRT display (1920 characters); 75-key keyboard; and various disk storage capabilities depending upon the model. The Eagle II includes two 5.25" mini-floppy disks of 390kb storage capacity each." The entry goes on to say that a 7.5 or 10mb wichester was available for it, and that it was supplied with CP/M & CBASIC. Sounds like a pretty standard issue CP/M box, in vogue at the time. MSRP (in 1983) was $2,995. Eagle Computer was located in Los Gatos, CA. On Wed, 10 Mar 1999 15:07:43 -0600 Arfon Gryffydd <arfonrg(a)texas.net> writes: >No clue.... Big blue case...

It's just a plain black, one piece, dumb terminal. Nothing special. The most curious thing about it is the location of the DIP switches. They are under a removable cover above the keyboard. It makes it convenient if you are trying to talk to a system and aren't sure of the comm parameters. I do have a set of manuals. If you have any questions about settings or emulations, I'll look them up for you. I don't think there are *that* many around so, I'm gonna keep mine. Steve Robertson - <steverob(a)hotoffice.com>

Hazeltine?

by jlwest＠tseinc.com

>Anyone heard of a Hazeltine? Not sure of the model but I have a black >one piece terminal looking unit that I'm curious of the sentimental, >astetic or collector value of this brand of machine. Any input >appreciated and maybe there will be one up for adoption soon. Sure - Hazeltines in general but specifically the model 1500 were a "standard" of sorts for terminals long ago. I'd give it a home if no one else has an interest. It's not particularly rare at all, but has a sentimental value to probably most on the list here. If someone else here winds up getting it - keep in mind that I have a genuine hazeltine1500 manual if anyone needs it. Jay West

E&L Mini-Micro Designer

by fauradon＠pclink.com

OK, I've been soft brained lately. I do have a copy of the articles May, June and july 1976 (Last one is incomplete:(. If there is enough interest I can try to scan all I have and post it somewhere (I'm running low on web space so it might have to be somewhere else..). It's about ten double sided pages (I can renove the adds from the scans) My Dyna Micro came without any chips, they apparently have ben canibalized is there any way that I can obtain a 1702 with KEX??? Also if anyone has the July 1976 of Radio Electronics, the end of the article is at page 85, I'd love to get a scan of that... Thanks Francois

What classic equipment was rebadged?

by dpeschel＠u.washington.edu

I know that Company A would take one of Company B's products and stick a "Company A" label on it... that's what most people mean when they say "rebadging", I think. It's pretty easy to spot, if you can find one of Company B's products for sale. But I'm also wondering about the case in which Company A *hires* Company B to make a product, and may even deny that Company B did any of the work. Is that also called rebadging? What classic hardware/software companies were most famous for this? I've learned (from Allison and Megan's various posts) that Digital sometimes used other companies' stuff -- often at the cheap end of a line of products, I suspect. What about IBM? Wang? Microsoft? I'm thinking mostly of the 60's to early 80's. I don't need to ask about the current state of the computer industry, since I already *know* that it's near-total anarchy. You may wonder what brought this stream-of-consciousness eruption on. Every time I look at TI's calculator web site, I see that they state their calculators' features in terms of "bid specifications". Now I find that creepy, personally. I always thought that TI didn't care very much about its calculators (anyone see any vintage TI calculators to go with the fine HP machines at the last VCF?). But if TI puts bids out, then they care even less than I thought. Unless they have some perverse internal bid system? And that ties into the other reason I made this post. What does the computer industry look like from the companies' perspective? What sorts of nasty deals have gone on in back rooms? Big companies love to use terms like "OEM" or "supplier" but that doesn't even scratch the surface of a complex web of relationships. Then there's the even more intricate question of the *information* behind all of the energy (i.e., the source code, algorithms, proprietary techniques). Sometimes a high enough price will buy it; sometimes it isn't available for any price... wierd. I'll save the question about the quality of the finished product for next itme. :) Besides, I already think I know the answer: often the quality is the last priority on the list, and the customer gets the shaft. (At least lately. Maybe it was different 25 years ago.) Thanks for reading this ramble, -- Derek

vax, cdroms, etc

by jim＠calico.litterbox.com

Hi. I've finally got all the stuff to upgrade my vax to a level where I can hang it on my network. I have the external disk cable, I have a new 1gig drive to put in it. And of course, I have some questions. i 1. Does VMS 6.2 know about ISO9660 cdroms out of the box? 2. When doing a show dev on a VS3100/40, the cdrom drive should show up on the device list, right? (I suspect I goofed up the wiring on the CDROM case) 3. can someone answer conclusively for me whether the vaxstation expects the disk to have parity enabled? The lists I've read don't seem very sure. 4. anything special about configuring cmu? I've gotten UCX to work in a past life as a VMS sysadmin. As always, I appreciate any answers y'all can give me. -- Jim Strickland jim(a)DIESPAMMERSCUMcalico.litterbox.com ----------------------------------------------------------------------- Vote Meadocrat!

Burst Nibbler?

by geoffrob＠stmarks.pp.catholic.edu.au

Hi all, Have a friend that has acquired a heavily optioned up Commodore 64. He is not very clued up on computers in general, but he has some strange options fitted. There is some sort of accelerator board built in to his 1541 drive. Unfortunately, for it to work, it evidently needs a disk with something called (I think) Burst Nibbler on it. Seems to be associated with something called Dolphin DOS, possibly on the same disk. Problem is that he doesn't have the disk, seems he bought the machine and many boxes of disks at auction, but a pile of other disks went to someone else. He was able to find the original owner, who confirmed that he needs this particular disk to make the fast loader work, but it seems it was with the stuff he didn't get.. I know just enough about C64's to avoid them like the plague, however I would like to help him if I could.. Anyone out there know more about this, especially in Oz? I'd be happy to cover the costs of copying/shipping a floppy. Cheers Geoff Roberts Computer Systems Manager Saint Mark's College Port Pirie, South Australia.

I haven't done anything with this. chkasm.c is source for a program that checks an HP21xx absolute binary tape to make sure it is OK with its checksums. I haven't done anything with this either. Turns out Jeff did most of his development work under MS-DOS, and I think it probably works best there. I don't know what C compiler he used for MS-DOS. For Un*x, there is the file mkunix which contains commands to compile this stuff. It's not exactly a shell script but may be used as standard input to a shell. Building e21 under FreeBSD requires that you remove -DTERMIOS, and you will then notice that the simulator's prompts are wacky because it puts the tty >from which it is run into raw mode and leaves it that way. I have some patches that make it switch the tty back and forth as needed but they introduce another bug, namely the simulator exits when the simulated 21xx halts. Oops. OK, so now supposing you've got it built, go get something else: http://oscar.taurus.com/~jeff/2100/hpbasic/basic1.abs That's an absolute paper tape image for a single-user standalone BASIC interpreter that will work with the simulator. Now run e21, tell it to LOAD basic1.abs, and then to RUN. Case is important for the simulator's commands. That should get you running the standalone BASIC. Fun, huh? When you get tired of this, type BYE to the BASIC interpreter, and it should drop you back to the simulator's U2100> command prompt. Q will exit the simulator. -Frank McConnell

I have to sympathise with Amiga Inc though. It wasn't easy when they split from their OS Partner around a week before the show. All the hype about the announcement and then they are forced to abandon half of it, leaving just some vague references to a superchip, development boxes and a schedule that was impossible to meet. Personally I think the Amiga has been slowly dying for a number of years. Admittedly there is not the sense of gloom as in 1996 but the "Classic" market is gradually shrinking. In the UK, Amiga Format readership has dropped to just 14,644. However it is hardly doom and gloom; Netscape is being ported to the Amiga under the name "AMozillaX"; Power Computing are set to release a revised version of the A5000 that uses the Escona G3 accelerator; and AmigaOS 3.5 screenshots have been shown for the first time (www.amiga.de). >Well, basically right, but as Tony pointed out, on the DEC Pro POS is >actually P/OS, and I can't remember if the Amigoid POS is POS or P-OS, but >it was to also run on a Pios One :^) <GAMESHOW HOST>Ooooh, you were so close.

Scanning old manuals

by edick＠idcomm.com

I use some software called TypeMaster Pro, or something very close to that with an old monochrome legal size scanner with sheetfeeder, namely a Microtek 300, which I've had for about 10 years. I normally plunked a manual in the feeder (once the binding was cut off) and scanned all the odd, then all the even pages. It rejects the pictures, of course, but you only have to nurse it through the first 10 or so pages, by which time it's learned the font and punctuations in common use in the manual and can do the rest more or less by itself. Unfortunately it has to be retrained for the second pass. What it does is pretty slick, though, in that it looks at the alignment and actually straightens out a sheet which has been fed crooked. It can't replace text it didn't see, but it does a pretty good job. One of my colleagues made a quick machine readable copy of the State's revised statutes in order to investigate a case in which he was involved. It required less than half a day for him to do that.

wither the MAC address of DELQNA?

If it's wrong, someone correct me it's something I haven't done in 6 years. The DEQNA and DELQA are identical in the console command and addresses needed to dump the MAC.

This is what I have been doing.... I gave up on JPG and GIF even though they are directly supported by the major browsers because the image quality wasn't there and file sizes were getting out of hand when attempts were made to preserve image quality. TIFF on the other hand, works well, and is quite compressable. Pretty much consigns you to putting them in a PDF though, which isn't all that evil I suppose. The one attractive thing we loose by creating 60meg PDF files is the ability to browse pages without downloading the entire thing....

Did you do that 500+ page manual by hand or with the sheet feeder? :-) Right now I have a stock HP Scanjet 4C, but am considering investing in a ledger-size scanner with a decent sheet feeder so I can archive not only my manuals, but my printsets as well. >Eric Jim
